What\/Why?<\/strong> I want to write a simple Python script that warns me if crypto price data (e.g., BTC) crosses a certain threshold. This can be useful for trading or some other apps, so I thought it would be fun to do it. <\/p>\n

The tutorial in front of you simply documents my learnings on creating a sinus tone in my Jupyter Notebook—so it may benefit you as well. <\/p>\n

If you want the whole tutorial on my mini project, you can check it out here on the Finxter blog: <\/p>\n

Challenge<\/h2>\n

\"\ud83d\udcac\" Challenge<\/strong>: Write Python code in a Jupyter Notebook that creates a sinus tone when executed. <\/p>\n

Solution<\/h2>\n

The easy way to solve this challenge is the following. \"\ud83d\udc47\"<\/p>\n

This code creates a sine wave with a frequency of 500 Hz and plays it in the IPython environment. The wave is created using the NumPy library by specifying the frequency and the length of the wave (15000*2). The rate of the wave is set to 10000 Hz and autoplay is set to True<\/code> so that the wave will start playing immediately.<\/p>\n

import numpy as np\nfrom IPython.display import Audio # Create the tone as a NumPy Sinus Wave\nwave = np.sin(2*np.pi*500*np.arange(15000*2)\/15000) # Play the Sinus Wave (tone)\nAudio(wave, rate=10000, autoplay=True)<\/pre>\n
This generates the following beep sound in your Jupyter Notebook:<\/p>\n
# Play the Sinus Wave (tone)\nAudio(wave, rate=20000, autoplay=True)<\/pre>\n
The beep sound tone gets higher:<\/p>\n
\n

But what if you don’t have a Jupyter notebook but a normal Python script (Win\/Linux\/macOS)?<\/p>\n
In that case, you cannot use the IPython<\/code> library. Instead, follow the steps outlined in the following tutorial on the Finxter blog—you still can play beep sounds!<\/p>\n
